Monomorphization
Truffle has an automatic approach to monomorphization (also known as “splitting”). For more information about the benefits of monomorphization, continue reading to Monomorphization Use Cases.
It is controlled by the Splitting
engine option and is on by default.
Adding --engine.Splitting=false
to your command line will disable it.
The heuristic relies on information from the language implementation to guide the decisions. To find out more about how to use the new approach in your language implementation, refer to the Reporting Polymorphism guide.
For more details on how the new approach works, see the Splitting guide.
